Cheeps Disposal Inc. plans to install a hazardous-waste incinerator to burn liquid and solid waste materials. The exhaust gas from the incinerator will pass through a quench spray, then into a Venturi scrubber, and finally though a packed bed scrubber. Caustic added to the scrubbing liquor will remove any HCl from the flue gas and will control the pH of the scrubbing liquor. The uncontrolled particulate emissions leaving the incinerator are estimated to be 1100 kg/h (maximum average). Local air pollution regulations state that particulate emissions must not exceed 10 kg/h. Using the following data, estimate the particulate collection efficiency of the Venturi scrubber
(USEPA-84/03, p. 9-8).
